Whole Brain Emulation

TagLast edit: 1 Oct 2020 0:02 UTC by Swimmer963

Whole Brain Emulation or WBE is a proposed technique which involves transferring the information contained within a brain onto a computing substrate. The brain can then be simulated, creating a machine intelligence. The concept is often discussed in context of scanning the brain of a person, known as mind uploading.

WBE is sometimes seen as an easy way to creating intelligent computers, as the only innovations necessary are greatly increased processor speed and scanning resolution. Advocates of WBE claim technological improvement rates such as Moore’s law will make WBE inevitable.

The exact level of detail required for an accurate simulation of a brain’s mind is presently uncertain, and will determine the difficulty of creating WBE. The feasibility of such a project has been examined in detail in Future of Humanity Institute’s Whole Brain Emulation: A Roadmap. The Roadmap concluded that a human brain emulation would be possible before mid-century, providing that current technology trends kept up and providing that there would be sufficient investments.

Several approaches for WBE have been suggested:

A digitally emulated brain could have several advantages over a biological one5. It might be able to run faster than biological brains, copy itself, and take advantage of backups while experimenting with self-modification.

Whole brain emulation will also create a number of ethical challenges relating to the nature of personhood, rights, and social inequality. Robin Hanson proposes that an uploaded mind might copy itself to work until the cost of running a copy was that of its labour, vastly increasing the amount of wealth in the world but also causing mass unemployment6. The ability to copy uploads could also lead to drastic changes in society’s values, with the values of the uploads that got copied the most coming to dominate.

An emulated-brain populated world could hold severe negative consequences, such as:
